Two FBI agents who testified before a House subcommittee on Thursday had their security clearances revoked due to their conduct related to the January 6th attack on the U.S. Capitol, according to a letter from the FBI to Congress. The letter was sent ahead of the hearing led by Rep. Jim Jordan, R-Ohio, and the revocation was due to their allegiance to the United States being called into question. The FBI is continuing to investigate the attack and has charged more than 400 people in connection with the insurrection.
